SPECIFICATION forming part of Letters Patent N o. 681,171, `dated August 20, 1901.

,ip Application tiled December 13, 1900. Serial No. 39,717. (No model.)

\ To all whom it may concern.- table or rest for the wheel-being operated illustrated in the drawings, and incorporated in :the claims.

` In the accompanying drawings, Figure 1 is `a perspective View of the machine complete constructed in accordance with the presen-t.-

invention and shown applied to and snp- E ported upon apost or standard. Fig. 2 is an l Be it known that LjMIcI-IAEL L. KNUPP, a citizen of the United States,residing atToledo,

` 1 in the county of Cumberland and State of Illi-` nois, have invented a certain new and useful Wheel-wright-'Machine, of which the follow- 1 l ing is a specification, reference being had therein to the accompanying drawings.

This invention relates to wheelwrightmafchines, and has for its object to provide a simple, cheap, and efcient hand-operat-ed machine adapted to be fastened and supported l upon a suitable post or wall, the machine embodyingmeans for drilling the felly and tire `of a vehicle-wheel to receive the tire-retaining bolts, means for countersinking the tire,

l y so that the tapered heads of the bolts maybe 1 `seated iush,means for turning the nuts on and off the bolts, and means for gripping the bolts,

so as to prevent the same from turning in the `rim and tire during the operation of turning l l. the nuts on and off. The parts are so comjbined and arranged that the several features t willnot interfere with each other during the `Operationof oneor more ofthem.

\ y The detailed objects and advantages of the invention will appear more fully in thecourse of the ensuingdescription.

. The invention consists in certain novel feaf tures anddetails of construction and arrangement of parts, as hereinafter fully described,

yenlarged vertical sectional view of the same. Fig. 3 is a detail perspective view of the y wrench.

i Similar numerals of reference designate corl responding parts in all the figures of the drawings.

Referring to the drawings, l designates a post to which the improved machine is shown applied. The machine may be applied to a wall or other convenient form of' support. 'The machine comprises,essentially,a frame 2, provided with an upper horizontal extension .3, a lower horizontal extension 4, forming a upon, and an intermediate horizontal extension 5, the extensions 4 and 5 being connected by a vertical web or strengthening-rib 6, and the extensions 3 and 5 being connected by parallel side portions or cheek-pieces 7, forming bearings for the main driving -shaft S, Which is equipped with a handlever 9, arranged at one side of the machine.

The extensions 3 and 5 form bearings for a `vertical drill-shaft 10, adapted to be moved up and down by means of a hand-operated feed-lever 1l, fulcrurned at l2 on an oscillatory f ulcrurn-post 13, pivotally mounted at 14 on the frame. The upper extremity of the drill-shaft 10 is annularly recessed orY ing the feed-lever 11 and pivotally connected thereto by means of a pin or bolt 20. The shaft l0 thus has a swiveled connection with the yoke 19, which enables the shaft to be continuously driven or rotated as it is fed downward by depressing the lever 11. The feed-lever 11 is normally upheld by means of acontractible spring 2l, having one end attached to the lever and its opposite end connected to the overhanging arm 22 of a bracket 23, secured to the post l or otherconvenient support.

The drill-shaft lO is provided with a longitudinal groove or keyway 24, in which Works the key 25 of a spur gear-Wheel 26, resting upon the intermediate extension 5 of the frame and maintained in place thereon by means of aspacing-sleeve 27, which surrounds the shaft 10 and is interposed between the i. gear-wheel 26 and the upper horizontal extension 3 of the frame. The wheel 26 intermeshes with another spur gear-wheel28, fast on the upper end of a counter-shaft 29, which has its bearings in the portions 4 and 5 of the frame, as clearly shown in Fig. 2. Rigidly associated with the wheel 28 is a bevel-pinion 30, which meshes with and is driven by a bevel gear-wheel 31, fast on the driving-shaft S, hereinabove referred to. By the mechanism described rotary motion is imparted to` 29 is a spur gear-Wheel 35, which intermeshes f with another spur gear-wheel 36, both of said4 wheels being arranged beneath the table or wheel-rest 4. Located beneath said Wheels is afhou-sing-.plate 37, securedby means ofl and provided Iwith sockets or-openings 39 and .40, one-to receive anaxi'al lextension-of the gear-W'he'el-BG' and the other `to receive the end ofthe counter-shaft 29. The-wheel 36 is locatedjim mediately beneath the drill and is provided with anfupwardi-axial extension-or huh 41, whichhas a recess 42, of irregular cross-section-alshape, forming'a socket to receive the correspondinglyshapedshankX43 of a nutsocket or wrench '44. The shank 43 and recess-*42 are ypreferably square incrosssec= i tionand'tape'r, so as toenable the wrench tobe quickly seatedy in and rotatably connected with the Wheel 36 Eandi'eadily removed therefrom Whe'unot needed.

Inordei to prevent the tirebolts fron-1 turn-- ing as the nuts are tu rned'thereon or removedv therefrom-I provide a boltgrippinglever45,' adapted to be operated by handandpivot ally lmounted at lits in ner end upon'a pin=or\ bolt546, held `yby one^or more ears 474 on'the machine-frame. At an intermediate point in its length the lever 45 is provided witha boltgrijp 48,-preferably consistingof alat-f erali extension or lug having its lower endl notched'or fashioned insuchshape as to -pro-y vide a plurality `ofpoints orangles49, which' will indent theheadof 4the bolt sufficiently to obtaina-positive grip thereon and prevent the :rotation of the bolt as the nutis screwed` thereon or turned therefrom. is fulernmed ou a vertical-aXis,-so thatit may beswunglaterally out of theway'when not requir'ech'but is also mounted with sufficient looseness to enable it to be depressed "and brought intofengagement With=the tire-bolts;-

Fromithe'foregoing description' it- Will bel seenfthat by means of the machine herein'- above described, and illustrated inthe drawings, a-vehicle-wheel tireI and fellyinay be readily drilled andthe tire count'ersunk'to're-A ceive the ordinary tire-bolts;y alsorthatthel f nuts Vmay be turned ion or off thebolts lwith The lever 45 the aid of the machine an dlwi'thoutA the neces-l sity'of 'employing Aan eXtra ivrenchfor that purpose; also, that the bolts may be rmly gripped and held against rotation while placing the nuts thereon or removing the same therefrom.v In drilling `the bolt-holes inthe rim and-tire'the Wrench 44 may be detached, so as to allow the wheel-felly to rest on the table 4. After the holes are all drilled and the bolts 'placed therein the wrench is associated with the gear-Wheel 36 and the nuts placed therein one by one, the machine beingoperatedby the hand crank or lever 9, thus enabling the nuts to be readily turned upon'their respective bolts, thus doing away with the necessity of handling the nuts with the fingers.

i The machine isv simple in constructionand ,will e ffectively perform ithe Work for which? iti is designed.-

I donot'desireto'be limited to theeXact` details of construction hereinabove -set-forth but reserve lthe right toi change,- modify, or

vary the construction within Athe scope ofthis invention.

Havingthus describedthe invention, what isi claimed as new, anddesired to-be secured by '-Letter's Patent, is-
